How to automate update of Access Keys for POWER8

The other day, I’ve wrote about POWER8 ‘feature’ which requires from an administrator update of  access keys in order to keep a server eligible for the firmware upgrade POWER8 – No hardware maintenance-no firmware upgrade . An administrator needs to enter these every few months, if a maintenance contract is re-signed every few months. This can be a headache, or something bigger if someone runs multiple servers. There is a secret HMC function, which can update the keys automatically.

Create an LPAR with specific WWPNs

How to display the HMC iqyylog.log

In this post I give you a hint how to display a log which is usually used by IBM support to identify a serious hardware error. Such information usually can be found in HMC log called iqyylog. Usually, when you get that kind of hardware error, you involve IBM support. Very likely, they will ask for PE debug data. There is a way how to display the log by yourself. Remember, such information is very technical. But maybe you find it useful.

  • First, you need to create the hscpe account on the HMC (if you haven’t done it). You can find the process here.
  • Log in to the HMC GUI under hscpe account.
  • In the Service Management menu you find three new options available

If you click on View Management Console Logs, you are going to see the log.

This is very convenient when you get your POWER machine to the new location, and you want to install an operating system, for instance, IBM i or AIX, but you prefer to do it remotely.
